Thank you all for your comments!
Corlan, this time I used tripod and mirror up technique
And Live view too.
I have a sharpening action in PS so I use it all the time. It's just one parameter that I change from pic to pic, that's all.
Obviously, these photos could be taken with almost any DSLR, considering the size of these JPEG's. But! As I tend to take pictures having BIG PRINTS in mind I take them with the best camera and lenses - the D3x and ... the lens I have for now: 24-70/2.8. I'm sure though I'd get the results even better with my Linhof but here's the common problem with large format - the whole setup is large and heavy
I take out Linhof only when I know 100% that I have to take best of the best.
